Velocity system not working properly on my train!

Help and Feedback Scripting Support
#1

I would like to make this system to accelerate and deaccelerate at a normal rate!

The issue is that this system is increasing the speed drastically every time I press W and after a short bit it will stop. Any help would be great!

Code:

local seat = game.Players.LocalPlayer.Character.Humanoid.SeatPart
local vel = game.Players.LocalPlayer.Character.Humanoid.SeatPart.Parent.Base.BodyVelocity

local Velocity = script.Velocity

seat.Changed:connect(function(type)
	if type == "Throttle" then
		local Input = seat.Throttle
		repeat
			Velocity.Value = Velocity.Value + Input
			if Input*Velocity.Value/math.abs(Velocity.Value) == -1 then
				wait(1/script.Deceleration.Value)
			else
				wait(1/script.Acceleration.Value)
			end
			if Velocity.Value > script.MaxSpeed.Value then
				Velocity.Value = script.MaxSpeed.Value
			elseif Velocity.Value < 0 then
				Velocity.Value = 0
			end
			
		until seat.Throttle ~= Input
	end
end)

while script.Parent ~= nil do
	wait()
	vectorpower = script.MaxPower.Value*seat.CFrame.lookVector
	vel.MaxForce = Vector3.new(vectorpower.X>0 and vectorpower.X or -vectorpower.X,
		vectorpower.Y> 0 and vectorpower.Y or -vectorpower.Y,
		vectorpower.Z> 0 and vectorpower.Z or -vectorpower.Z
	)
	vel.Velocity = Velocity.Value*seat.CFrame.lookVector
end

I have been looking around but can’t seem to find a solution. all help given would be great!
